Porcine enzootic pneumonia is a chronic respiratory disease caused
by Mycoplasma hyopneumoniae, producing high morbidity rates
and great economic losses. This handbook attempts to update,
condense and simplify the large amount of available information
about porcine enzootic pneumonia, including a high number of
graphic contents to provide the veterinary surgeon with a handy tool
to fully understand, treat, control and prevent this disease.

Beatriz García-Morante

Beatriz García-Morante graduated from the Autonomous University of Barcelona (UAB)
with a degree in veterinary medicine in 2012, and gained an interuniversity Master’s
Degree in Advanced Immunology from the UAB and the University of Barcelona (UB) in
2013. She earned her PhD under the Government of Catalonia’s Industrial Doctorates Plan
in 2017, in a collaborative arrangement between the pharmaceutical industry and CRe-
SA (Centre de Recerca en Sanitat Animal; Centre for Animal Health Research) at IRTA
(Institut de Recerca i Tecnologia Agroalimentaries; Institute of Agri-Food Research and
Technology), located on the UAB campus. Her doctoral thesis sought improvements to
the experimental model for the study of Mycoplasma hyopneumoniae infection, under the
supervision of Dr Marina Sibila and Dr Joaquim Segalés. She has published articles in
national and international journals, and has also been a resident of the European College
of Porcine Health and Management (ECPHM) since 2015, mentored by Dr Sergio López
and Dr Joaquim Segalés.

Joaquim Segalés

Joaquim Segalés graduated in veterinary medicine from the UAB in 1991 and was awarded
his PhD by the same university in 1996, after spending 15 months at the University
of Minnesota (UM) in the USA, codirected by Dr Mariano Domingo (UAB) and Dr Carlos
Pijoan (UM). He became a diplomate of the European College of Veterinary Pathologists
(ECVP) in 2000 and by the ECPHM in 2004. He is a founding member of the ECPHM and
was its president between 2013 and 2016. Dr Segalés is a tenured lecturer at the Department
of Animal Health and Anatomy of the Faculty of Veterinary Medicine at the UAB, and
he is also a researcher with CReSA–IRTA, where he was director between 2012 and 2017.
He participates in many Spanish and European research projects, and collaborates with
Spanish and international companies in the pig production sector. His research includes
porcine respiratory and reproductive syndrome virus (PRRSV), Haemophilus parasuis,
Aujeszky’s disease virus (ADV), Mycoplasma hyopneumoniae, hepatitis E virus, torque
teno sus virus (TTSuV), and diseases associated with porcine circovirus type 2 (PCV2). He
is coauthor of over 270 articles in international scientific journals, 10 chapters of internationally
acclaimed books, a book on pig necropsy, and 3 books on clinical cases in pigs.

Marina Sibila

Marina Sibila graduated in biological sciences from the UB in 1999. Under the supervision
of Dr Maria Calsamiglia, she completed her PhD on the molecular epidemiology of M.
hyopneumoniae infection at the Faculty of Veterinary Medicine of the UAB in 2004. She is
currently a researcher at CReSA-IRTA, where she is continuing her work on M. hyopneumoniae
and other pig pathogens, including PCV2, PRRSV, Haemophilus parasuis, Actinobacillus
pleuropneumoniae, Mycoplasma hyorhinis, and TTSuV. Her research includes
molecular epidemiology, the development of experimental models and diagnostic tools,
and vaccine efficacy studies. Dr Sibila collaborates in many Spanish and international
research projects, and she has published more than 60 scientific and educational articles.
She is also co-author of a book chapter on the evaluation of lung lesions in pigs at
the abattoir and a handbook of laboratory diagnosis in pigs. Dr Sibila has participated as
a speaker at various conferences in the sector, both in Spain and internationally, and her
teaching activities have included PhD courses and classes for a master’s degree in swine
health and production and directing various doctoral theses
